Cron problem swap.state



  • Hi guys,
    I'm having problems with Cron for a long period and it drive me crazy.

    Every 15 minutes I'm receiving e-mail from Pfsense with next text:


    X-Cron-Env: <shell= bin="" sh="">X-Cron-Env: <path= etc:="" bin:="" sbin:="" usr="" sbin="">X-Cron-Env: <home= var="" log="">X-Cron-Env: <logname=root>X-Cron-Env: <user=root>Warning: filesize(): stat failed for /var/squid/cache/swap.state in /usr/local/pkg/swapstate_check.php on line 47


    I guess I should mention that I do not have file  swap.state in /var/squid/cache (there are only 16 folders in named from 00 0A 0B….. 09).

    I'm not very god in programing but I'll do my best to tray to fallow you advices... if any :)

    My swapstate_check.php in folder /usr/local/pkg/ looks like this:


    #!/usr/local/bin/php -q

    Please help!!!

    It drives me nuts :D

  • I'm having the same problem, any solution for the problem?



  • That was fixed in Squid(2) in August 2013, but it seems was never applied to Squid3(.1 and .3).
    I just made a pull request to add the extra checks:
    https://github.com/pfsense/pfsense-packages/pull/724
    You should easily be able to hand-add the 2-line check to swapstate_check.php on your system and confirm it works.



  • Thanks!

    Best regards
