We are experiencing recurring cache issues on a series of MODX instances. 500 errors appear regularly (not everytime), blocking the sites.
The MODX folders are located on an NFS server. The web roots are mounted on 2 RedHat servers (Apache) in NFS v3 behind a KEMP loadbalancer doing SSLoffload.
Should we suspect a safe flock problem as mentioned in Strange and critical cache problem on shared hosting - #2 by markh Has anyone ever used an NFS mount? Would moving the cache folder to a local partition help? If so can we move the folder and configure it as it is done for the “core” folder?
Thanks for your advice
