Why does Airwave httpd process restarts continuously while Initializing Cache::FastMmap cache files?
The source of the problem is the size of the fastmmap/rogues_cache.
Airwave httpd process restarts continuously while Initializing Cache::FastMmap cache files you could find that in /var/log/httpd/error_log.
When the number of rogues on the system is plenty then the size of rogues_cache [/var/lib/airwave/cache/fastmmap/] file is expected to be large as show below.
The problem will re-appear any time httpd is restarted until the number of rogues has been reduced. Please make sure that we have some number other 0 for rogue’s data retention under rapids setup page to avoid this trouble in the future.
Deleting the fastmmap.size file (/var/airwave/cache/fastmmap.sizes) while the AMP is disabled should allow httpd and all the other services to complete the normal startup process when the AMP is re-enabled.
As we remove the /var/airwave/cache/fastmmap.sizes and enable amp services, the server will be restored successfully without any crash as show below.
