Subject: [dpdk-dev] [Bug 560] excessive numbers of open file handles kept open
Date: Mon, 19 Oct 2020 17:08:52 +0000 [thread overview]
Message-ID: <bug-560-3@http.bugs.dpdk.org/> (raw)
https://bugs.dpdk.org/show_bug.cgi?id=560
Bug ID: 560
Summary: excessive numbers of open file handles kept open
Product: DPDK
Version: 20.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: core
Assignee: dev@dpdk.org
Reporter: stephen@networkplumber.org
Target Milestone: ---
The DPDK memory management of huge pages leaves many open file handles which
may break applications because of running out file descriptors or use of legacy
API's like select that can only handle 1024 fds.
The root cause is in the hugepage segment handling code.
Example.
# lsof -p PID | grep -c rtemap
1494
Each fd there is counted twice, once as an fd, and once as an mmap.
So in this case 747 file rtemap files are left open.
