Futexwakeup error on synology DS215+

_yo · May 4, 2026, 3:55pm

Bonjour à tous,

What is the problem you are having with rclone?

I use rclone on a Synology NAS (DS215+) for backing up NAS datas on an union remote on multiple providers.
There are 3 planified tasks on what i call a session on the NAS :

update rclone
backup data on union
report occupation percentage of each remote

On the last session, step 1 updates rclone itself from 1.73.5 to 1.74.0
And from that time, using rclone outputs a lot of error like described below

Run the command 'rclone version' and share the full output of the command.

Nas version :
SYNOLOGY DS215+
Version: 7.1.1-42962 Update 9

’rclone version’ gives error.

Which cloud storage system are you using? (eg Google Drive)

union remote on pCloud, mega and koofr providers

The command you were trying to run (eg `rclone copy /tmp remote:tmp`)

It's scripted but something like

rclone sync /volume1 union:vador/volume1

The rclone config contents with secrets removed.

[pcloudXxxx]
type = pcloud
client_id = ----
client_secret = ----
hostname = eapi.pcloud.com
token = {"access_token":"----","token_type":"bearer","expiry":"0001-01-01T00:00:00Z"}

[koofrXxxx]
type = koofr
provider = koofr
user = ----
password = ----

[megaXxxx]
type = mega
user = ----
pass = ----

[union]
type = union
upstreams = koofrXxxx: megaXxxx: pcloudXxxx:root
create_policy = mfs

A log from the command with the `-vv` flag

The log returned in synology planified task result mail.

Could you tell me what can i do ?
First step trying to revert to 1.73.5 ?

rclone selfupdate --version 1.73.5

gives also futexwakeup errors...

FYI, the mail from the step 1 update :

Hi asdffdsa,

welcome to the forum

Thanks.

Don't know how to remove rclone.
But I tried to remove /usr/bin/rclone and then how i firstly installed rclone :

based on rclone documenation, that version is not supported.

minesheep · May 4, 2026, 7:30pm

Maybe I have mistaken but isn't 3.10.108 > 3.2?

asdffdsa · May 4, 2026, 7:31pm

truth is, i am not 100% sure now.
lol, i am half-monkey, math is not my strong point.

This is a bug in the ancient Synology kernel. The Go developers have got a workaround which has been scheduled for back port into go1.26 which rclone 1.74 is built with.

NeedsFix compiler/runtime FixPending BugReport

@calmh [report](https://github.com/golang/go/issues/77730#issuecomment-399366264…7): We seem to be seeing the same crash on armv7 -- or should I file this separately? https://github.com/syncthing/syncthing/issues/10587 The return code is slightly different: ``` $ syncthing --version futexwakeup addr=0x4458b24 returned -22 16:54:03 [49/305] SIGSEGV: segmentation violation PC=0xc7f02c m=0 sigcode=1 addr=0x1006 ``` @Rongronggg9 [explains](https://github.com/golang/go/issues/77730#issuecomment-3995018983): No, these crashes on armv7 are completely different. Arm is an arch that uses `include/uapi/asm-generic/errno.h`. The root cause lies in Synology's ancient kernel. They had a faithful belief that they were cleverer than upstream kernel developers and added vendor (!) syscalls to their kernel. Not only did they add vendor syscalls, but they also forgot to leave enough reserved space to avoid conflict with the newly introduced syscall numbers of the upstream kernel. This is literally the most cursed thing you've ever seen in the Linux world. They should really have used ioctl or so... ```asm CALL(sys_SYNOUtime) /* 402 */ CALL(sys_SYNOArchiveBit) /* 403 */ CALL(sys_recvfile) /* 404 */ CALL(sys_SYNOMTDAlloc) /* 405 */ CALL(sys_SYNOCaselessStat64) /* 406 */ CALL(sys_SYNOCaselessLStat64) /* 407 */ CALL(sys_ni_syscall) /* 408 */ CALL(sys_ni_syscall) /* 409 */ CALL(sys_SYNOEcryptName) /* 410 */ CALL(sys_SYNODecryptName) /* 411 */ CALL(sys_SYNOACLCheckPerm) /* 412 */ CALL(sys_SYNOACLIsSupport) /* 413 */ CALL(sys_SYNOACLGetPerm) /* 414 */ CALL(sys_SYNOFlushAggregate) /* 415 */ CALL(sys_ni_syscall) /* 416 */ CALL(sys_ni_syscall) /* 417 */ CALL(sys_ni_syscall) /* 418 */ CALL(sys_SYNOStat64) /* 419 */ CALL(sys_SYNOFStat64) /* 420 */ CALL(sys_SYNOLStat64) /* 421 */ CALL(sys_SYNONotifyInit) /* 422 */ CALL(sys_SYNONotifyAddWatch) /* 423 */ CALL(sys_SYNONotifyRemoveWatch) /* 424 */ CALL(sys_SYNONotifyAddWatch32) /* 425 */ CALL(sys_SYNONotifyRemoveWatch32) /* 426 */ CALL(sys_SYNOArchiveOverwrite) /* 427 */ ``` (https://global.synologydownload.com/download/ToolChain/Synology%20NAS%20GPL%20Source/7.1.1-42962/armada370/linux-3.x.txz arch/arm/kernel/calls.S) ``` # 402 is unused 403 common clock_gettime64 sys_clock_gettime 404 common clock_settime64 sys_clock_settime 405 common clock_adjtime64 sys_clock_adjtime 406 common clock_getres_time64 sys_clock_getres 407 common clock_nanosleep_time64 sys_clock_nanosleep 408 common timer_gettime64 sys_timer_gettime 409 common timer_settime64 sys_timer_settime 410 common timerfd_gettime64 sys_timerfd_gettime 411 common timerfd_settime64 sys_timerfd_settime 412 common utimensat_time64 sys_utimensat 413 common pselect6_time64 sys_pselect6 414 common ppoll_time64 sys_ppoll 416 common io_pgetevents_time64 sys_io_pgetevents 417 common recvmmsg_time64 sys_recvmmsg 418 common mq_timedsend_time64 sys_mq_timedsend 419 common mq_timedreceive_time64 sys_mq_timedreceive 420 common semtimedop_time64 sys_semtimedop 421 common rt_sigtimedwait_time64 sys_rt_sigtimedwait 422 common futex_time64 sys_futex 423 common sched_rr_get_interval_time64 sys_sched_rr_get_interval 424 common pidfd_send_signal sys_pidfd_send_signal 425 common io_uring_setup sys_io_uring_setup 426 common io_uring_enter sys_io_uring_enter 427 common io_uring_register sys_io_uring_register ``` (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/tools/syscall.tbl?h=v7.0-rc2)

So with a bit of luck this will be fixed by the time we release 1.74.1.

In the meantime use an older rclone or build yourself a fixed go and compile rclone with that.

_yo · May 5, 2026, 6:27am

The sync is OK with 1.73.5.
And I'll wait for 1.74.1.
As i understand (a problem in go), it could be good.

Thanks a lot to all : jojo, minesheep and nick

ncw · May 5, 2026, 3:01pm

@_yo We've got a Go security update to do so we'll be making 1.74.1 on 8th May. I'm not sure whether this fix will be in the new Go version - they haven't released the changelog yet - give it a go when it comes out

ncw · May 7, 2026, 10:38am

This fix will definitely be in go1.26.3 so will definitely be in rclone 1.74.1 released tomorrow most likely

_yo · May 7, 2026, 10:53am

Thank you Nick and thanks to Go dev team. I'll try when available.
