Sessions crash, how to fix?

Question

memcached

I store sessions in memcached, they crash periodically. The first thought was that it simply overwrites the data, but a maximum of 50% is used from the allocated gigabyte of memory. I thought maybe the session is rotten and the garbage collector kills it, but no, increasing the session lifetime did not solve the problem. Tell me which way to look?

Answer 1

Perhaps the process is restarted (due to OOM?). Therefore, the data is overwritten.
