[asterisk-bugs] [JIRA] (ASTERISK-25837) Asterisk freeze - probable deadlock

[Jean Aunis - Prescom (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-25837?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=229855#comment-229855 ] 

Jean Aunis - Prescom commented on ASTERISK-25837:
-------------------------------------------------

The filesystem if of type XFS, we did not encounter any problem with it.
But I forgot to point out that we are not recording the calls to regular files : MixMonitor writes to a Unix FIFO (previously created with mkfifo), and the FIFO is immediately read by another channel with Playback.
