What's VA exhaustion?
Virtual address space.
If you were to open something like top, you'd a 'Virt' field besides the process.
For 32bit apps, there's 4GB limit for that value, once the app reaches that limit, new memory allocations fail, leading to various odd failures, sometimes even crashes.
In /proc you'll see that value for a process in the status file under VmSize.
