[Devel] Node Crashes on 64 bit owing to a single file.

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.

would be very helpfull! 

Thanks,
