** [tickets:#2215] log: write_log_record_hdl, fileclose_hdl get bad file
descriptor**
**Status:** fixed
**Milestone:** 5.0.2
**Created:** Fri Dec 02, 2016 10:52 AM UTC by Vu Minh Nguyen
**Last Updated:** Wed Dec 07, 2016 09:21 AM UTC
**Owner:** nobody
Steps to procedure:
1) Modify `saLogstreamLogFileFormat` attribute value
2) Modify `saLogstreamLogFileFormat` attribute value again
( Or write a log record to that log stream)
Here is what will happen in `IMM apply callback` at step (2):
a1) Close the old file
a2) Create the new file
If at step #a1 - close old file gets `TIMEOUT`, the main thread will give up
creating new file at step #a2.
But note that, `TIMEOUT` means the closing the file is in progress handled by
`log file handle` thread.
So, when going next with step #2 above, will get `bad file descriptor` as
performing close on the file which is already closed.
Below is the syslog info:
