i have a strange issue on asterisk 13.25.0 and centos 7:
i was grep ing for a phone number in /var/log/cdr-csv/Master.csv which was about 670MB; looks like it was not rotated in a while. this caused most of the sip peers to go unreachable and after a few seconds, they were reachable again.
the issue wont happen on smaller context.csv files
i was able to duplicate the issue after hours the load average as per top cmd was around 0.5 while i was running the grep cmd
i have since then rotated the Master.csv file
- anyone have any ideas?
- is this a known issue? should i be on the look out for any such large file searches?
- any suggestions, information is appreciated.
It sounds like you found the solution, manually, but to automate this you could consider a patch into CDR subsystem which emits warnings when there are significant delays in CDR processing, add a note to the cdr.conf.sample file about large CDR CSV files, or try out CDR batch mode to buffer CDRs (see cdr.conf for details.)
Non-Asterisk solutions are also available for watching file and directory sizes, emailing you alerts, etc.
Peers got unreachable by doing a grep search to a CSV file ?
Is this a virtual machine?
It sounds like there may be inadequate physical memory.
Thanks for the responses, yes, this is on a virtual machine.
According to fee and top cmds:
12137600kb total mem
You need the information from the host, not the virtual machine.
Ideally you wnat to set the virtual machine size to be a value that can be 100% committed against physical memory on the host. I think you are thrashing the host.
Also, I think the units are probably kB, not kb (factor of 8 difference)
