[Touch-packages] [Bug 1874824] Re: pgrep reports error "cannot allocate" when run without stack limit
I tested procps/groovy-proposed,now 2:3.3.16-5ubuntu2.1 amd64. I have repeated pgrep and pkill commands that caused the bug before. They do work with the proposed package. ** Tags removed: verification-needed-groovy ** Tags added: verification-done-groovy -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to procps in Ubuntu. https://bugs.launchpad.net/bugs/1874824 Title: pgrep reports error "cannot allocate" when run without stack limit Status in procps package in Ubuntu: Fix Released Status in procps source package in Focal: Fix Committed Status in procps source package in Groovy: Fix Committed Status in procps source package in Hirsute: Fix Released Status in procps package in Debian: New Bug description: [Impact] - Users who have ulimit set high would see either slow or failed pgrep and pkill commands - Users who have ulimit set to unlimited would see failed pgrep and pkill commands - This bug occurs because the behavior of sysconf(_SC_ARG_MAX) changed with a newer version of the kernel.
