While running a sync of RHEL 7 I am seeing it cap out around 1020 open files. I'm curious if this can still be produced on 6.10.6, and which repo specifically was being tested (I know it said "any" repo, but nonetheless) We've fixed a few file leak bugs lately upstream, I believe at least some of those patches are already in 6.10.6. The Pulp upstream bug status is at closed. Updating the external tracker on this bug. All upstream Pulp bugs are at MODIFIED+. Moving this bug to POST. Setting it back to NEW because as I said I don't think the small bug makes any real difference. All upstream Pulp bugs are at MODIFIED+. Moving this bug to POST. Brian, I am unable to reproduce any issues without an http proxy in the loop, and combined with the two reports and the traceback we can probably conclude that it is a necessary component of the bug. I now have some results (which are attached) from using this command to sync the repo https://cdn.redhat.com/content/dist/rhel8/8/x86_64/baseos/os/ with no HTTP proxy using the following command: watch -t -n 10 "(date '+TIME:%H:%M:%S' ; lsof -a -u pulp -n -d ^mem -d ^cwd -d ^rtd -d ^txt -d ^DEL | wc -l) | tee -a /tmp/pulp_nofile_sync" Could you get results of the same command running through the duration of the sync, syncing the same repository, under an HTTP proxy, so that we can compare them?file:///home/dalley/devel/pulp_nofile_sync Created attachment 1895482 [details]

Description of problem: In satellite 6.10.4, while syncing any repository, the error getting is: [Errno 24] too many open files after some time syncing. Version-Release number of selected component (if applicable): 6.10.4 although the customer says, he faces the issue in 6.9 as well as 6.10.3 Steps to Reproduce: on Satellite 6.10.4 when syncing any repository. Actual results: [Errno 24] too many open files after some time syncing. Expected results: Repo should be synced. Additional info: Customer did try to fix it with the workaround which helped. But needs a fix or a deeper investigation. ~~~ checking the number of open files for the pulp user with watch -n1 -t "lsof -u pulp -n | wc -l" i reach over 4300 open files which the pulp processes doent seem to be prepared to: for i in $(ps waxu|grep ^pulp | awk '{print $2}') ; do prlimit --noheadings --pid $i --nofile; done returns 1024:4096 manually setting it to a higher value with: for i in $(ps waxu|grep ^pulp | awk '{print $2}') ; do prlimit --pid $i --nofile=4096:8192; done ~~~
