I have moved this over to the spine repo, but can you run spine in the readonly verbose mode to see what device is causing the above failure?
although I do not see this error always but frequently . I just run spine on main poller as well as on one of the remote poller and here I attach the output of read only and -V=5 i.e debug ..although this do not give me any clue
PFA remote poller spine run in versobse =5 and read only mode
PFA remote poller spine output run in verbose=5 and read only mode
attachment
I am not able to upload the output file ..I just do drag and drop and when I click mouse on comment the attachment is not there . any trick I need to use to upload the files
here I paste the output

we also encountered error in separate error log related to MySQL .

I also see some error related to segmentation fault being complained by spine.

Hey Check this similar ticket out https://github.com/Cacti/spine/issues/174 Try updating to 1.2.16 I know this has come up a few times
@bmfmancini :Thanks for help . we are in the process of updating cacti and spine to latest version ie 1.2.16 ..but I also see in the comments of ticket #174 that the reporter disabled some slow query log on the server (Problem solved changing some slow query log by PHP scripts. Thanks a lot! :)) although we have not enabled any such logs ..But lets see how does it behave after updating spine to 1.2.16
I come back after updating spine to 1.2.16
Dear Contributors,
we have a multi poller environment on cacti 1.2.14 with one master poller and 9 remote pollers . for the last few months we have been observing the poller time overshoot on all remote pollers , polling time reaching to 300s or more and when we check the logs we find a fatal error related to spine . because we have noticed a correlation with this error in the logs ad poller time overshooting , so I think this issue with spine is related with poller time overshoot.
PFB error that we see

cacti version - 1.2.14 spine version - 1.2.14 php - PHP 5.4.16 MySQL - mysql Ver 15.1 Distrib 5.5.65-MariaDB Red Hat Enterprise Linux Server release 7.8 (Maipo)
can you please help us as we see load , memory consumption , I/o stats all seems normal and only clue we have is the spine related error .
although I see in change log of cacti 1.2.16 , a similar bug is fixed but the error code is 11 whereas in my case it is 6 , which says no such device or address found . PFB bug fixed in changelog of 1.2.16
issue#3948: Spine 1.2.15 - Spine Encountered An Unhandled Exception Signal Number: '6' [11, Resource temporarily unavailable] (Spine thread)
Let me know if something is required from my side.
