I encounter a tremendous lot of errors (no 24) "could not open file". This is new after running the program for severals years and I cannot tell what I changed in my system.

 

snippet from file:

    Hello Bernd,

    Product version           : 5.74.0
    I see, never bother to check the version number savscan displays.

    You still get these errors? errno 24 is EMFILE (the per-process limit on the number of open file and message queue descriptors has been reached). Don't think that savscan would suddenly misbehave. might have a hint what the cause could be.

    Hi Bernd,

     

    That version is the sweep version, rather than the SAV version, which makes it slightly harder to trace back. (/opt/sophos-av/bin/savdstatus --version to get the SAV version)

     

    Having said that, that looks like the most recent release. It's possible that there is a file descriptor leak in that build, which had fixes for some security issues.

     

    Did the scan earlier have a lot of symlinks it was unable to follow (broken symlinks or lacking permission to follow)?

     

    Thanks,

    Douglas.

    the problem always starts with a tremendous amount of lacking permissions for cache-files or files in flatpack installations.

    I'm afraid that does sound like you might have hit a file descriptor leak.

     

    I'd suggest splitting up your savscan, and maybe fixing the broken symlinks, or excluding them.

    Thank you, I will try and fix the files.

    Best regards
