#2170 sssd_nss grows memory footprint when netgroups are requested
Closed: Fixed Opened by jhrozek.

Closed: Fixed
Reopen Issue

We found out that we didn't free a memory context where we should, which resulted in memory growth if the application requesting netgroups was a long-running one.

To reproduce:
1) Run a process that requests a netgroup periodically but doesn't exit between the attempts. Maybe a deamon, python interpreter might do as well.
2) Watch the sssd_nss memory footprint grow

changelog: => The SSSD did not free per-client allocated memory when netgroups were requested. As a consequence, if netgroups were used by a long-running application, the sssd_nss process grew large in memory consumption.
