Ligesh,
Would be nice to provide exact messages and details when you have an access.
Also please specify kernel version you use.

how did you strace it if you say that *ALL* applications start segfaulting?
strace doesn't segfault?
> The thing is, once this vps is stopped, the others are working fine. I think the problem is with a specific file because we did a backup in cpanel, destroyed the old vps, created a new one, and restored the cpanel backup. The server was working fine midway the restore, but it started segfaulting when we were halfway through the cpanel restore.

Thanks,
