Apache2 does not come up on (NAS SSLSessionCache DBM file)

Apache was not coming up. 

Error that was reported in error_log was 

Cannot create SSLSessionCache DBM file 

Google search with the above keywords gave a few results. But that was not applicable to this current scenario.

As part of debugging, pointed the logs directory to a local directory and 

apache came up fine.

The problem was because rpc.statd was not started after reboot 

This was confirmed from the following messages 

dmesg gives this

FS-Cache: Loaded
statd: server localhost not responding, timed out
lockd: cannot monitor 10.224.16.60
 Unix sysadmin started the rpc.statd process and apache came up fine without having to create logs in local directory

From man pages for rpc.stad

The rpc.statd server implements the NSM (Network Status Monitor) RPC protocol. This service is somewhat misnomed, since it doesn't actually provide active monitoring as one might suspect; instead, NSM implements a reboot notification service. It is used by the NFS file locking service, rpc.lockd, to implement lock recovery when the NFS server machine crashes and reboots.
