BIG IP 3600 hangs without notice
Hi everyone,
We have had an issue with one of our BIG IP 3600 systems acting as a web accelerator where it failed without notice and stopped passing traffic.
System version:
BIG-IP Version 9.4.8 355.0
Final Edition
Issue was fixed by clearing the cached contents with the usual commands:
wa_clear_cache
bigpipe profile http http-acceleration ramcache entry all delete
Last message found in pvac.log file is as follows:
Dec 3 19:01:31 xxxxxxxx WA Debug: ICCommHandler::sendConfigPushRequest handling SIGHUP, requesting SysConfig
This seems to be an scheduled task running every hour, not sure if it's a system task or something the customer has set up himself.
When it runs fine this is the output log:
Dec 3 05:01:21 xxxxxxx WA Debug: ICCommHandler::sendConfigPushRequest handling SIGHUP, requesting SysConfig

Is this debug familiar to anyone?,
Notice also that the output of the bigstart status for pvac process shows quite a few restarts.
[root@csf5c01:Active] log bigstart status pvac
pvac run (pid 21047) 44 minutes, 106 starts
Thanks in advance,
