The aced process may leak file descriptors and/or memory when running for a long time without a restart and some error conditions such as: apd cannot connect to aced, aced cannot connect to backend server, exception happened when running out of memory, etc.
The impact of this issue is that service becomes unstable and either crashes or stops processing requests.
Failures may happen on connectivity issues; when aced loses a connection to apd or to backend server it may leak file descriptors and/or memory.
This issue has no workaround at this time.
The aced daemon now has several fixes to avoid memory/FDs leaks. It also restarts child processes gracefully if any failure occurs.
