Symptoms

In OpenSAFfire 6.2, when running an Software Management Framework (SMF) Campaign, File Descriptors (FDs) are leaked by osafsmfd until it crashes due to exceeding the Operating System enforced open-files limit.

SMF Campaigns are used to update OpenSAFfire and/or the applications utilizing the OpenSAFfire High Availability Application Programming Interfaces (APIs) while maintaining a level of service availability.

The easiest way to determine if an FD leak has occured, is to check the list of open FDs for the osafsmfd process before and after the Campaign is executed.

It can be observed that FDs 23 to 36 were opened during the campaign and have not been released.  Repeat runs of the SMF Campaigns result in further FDs to be leaked.
