Description Casey Bodley 2019-08-13 12:50:23 UTC

Description of problem:

Some errors from accept() are incorrectly thrown as exceptions, which are not caught and terminate the process. One such error is EMFILE (Too many open files) and is easy to reproduce with ulimit.


Version-Release number of selected component (if applicable):


How reproducible:

Always


Steps to Reproduce:
1. Run radosgw with a small number of file descriptors, ie 'ulimit -n 128'
2. Execute several client requests on different connections

Actual results:

radosgw terminates with an uncaught exception

Expected results:

radosgw logs an error and continues trying to accept connections
