I am getting the following log:
OS-SHMWIN-3-ALLOC_ARENA_FAILEDSHMWIN: Failed to allocate new arena from the server : 'SHMWIN_SVR' detected the 'fatal' condition 'VM is exhausted or totally fragmented'
Is it memory leak bug or something else?

Try reloading the standby and when it comes up initiate the RP switchover.

This error indicates that the system is running out of space in the shared memory region. It would be the best to capture "sh shmwin summary [location <location>]" and open a TAC SR.

will reload help ?
just want to do some temporary solution while waiting for SMARTNET to be purchased :)
el 09-12-2016 01:55 AM
yes, reload will clear the condition. I would also highly recommend to download and install the XR release 5.3.4, which should be available for download around September 22nd.
el 09-12-2016 02:00 AM
My platform is ASR 9006. So, i have 2 RSPs.
Reloading one by one RSP will do ? or i have to reload the whole system ?
el 09-12-2016 02:16 AM
if the error was reported on the RP, in that case you can simply initiate a failover from active to standby. If the error was reported on a LC, you have to reload the line card.
A system reload should not be required.

==============
Based on above log, it is happening on both RSP0 and RSP1.
So, one by one RP reload or all RP reload ? :)
el 09-12-2016 03:22 AM
Try reloading the standby and when it comes up initiate the RP switchover.
el 09-14-2016 07:43 PM
i just reload one by one and i don't see any alert anymore. Thanks !! :)
but not sure in longer run.
BTW, i forget some features to enable like:
1. isolation enable
2. nsr process-failures switchover
I am not sure if it will impact or interrupt the traffic to apply those command.
