GnuPG: OSError - Cannot allocate memory #263

Open manikanta-kondeti opened 5 years ago

Package details: python-gnupg==0.4.4 System specs: 4GB RAM, 2 core CPU

We're facing a problem with the GnuPG module.

We're using this module to encrypt our reports using a scheduler that triggers the report to generate them periodically.

Most of the times(once in 5 days) we're facing with the following issue: OSError - cannot allocate memory. Please help me out on how to diagnose and fix this problem.

OSError: [Errno 12] Cannot allocate memory

Your computer is out of memory. The gnupg module attempts to start another process but fails because the OS won't give it memory. The solution is to add more physical memory or allocate/increase the size of a swap partition.
