Thanks, the configuration changes once an hour or so. Typically, we have about 1000 active shared memory segments (yes, they are SHMs) attached to the httpd processes. For now, we’ll just have to implement a SHM clean-up in the start/stop wrappers until we can address the root cause or find a cleaner mitigation, which your patch might help with. - Mark
