Sophos Linux don't accept the configuration " UpdatePeriodMinutes "

Hi Henrique,

Please allow me to check on this and update you.

OK

Thanks

Hello Henrique RJ,

don't accept means you can set it but it is ignored? DouglasLeeder could tell whether the behaviour has indeed been changed.
BTW, just curious - what's your reason for choosing 24 hours?

I prefere 24h because I have 2GB memory and the frequent update cause system slowlli ( it cause problem with preload ).

If I adjust for 60 minutes the Sophos accept but for 1440 minutes didn't accept.

OK ?

Hi,

As far as I know, we haven't changed anything related to update period recently.

Please could you add the recent savlog output, to show the updates happening more frequently?

Thanks,

Douglas.

Look syslog ( /var/log/syslog ):

That's from syslog, not savlog, and only shows one update.

After an upgrade like that I'd expect one update after 5-10 minutes, then it should wait the UpdatePeriod before doing another update check.

savlogd ( /opt/sophos-av/bin/log )

nofile.io/.../savlogd

Sorry, I thought you would know how to view savlog:

/opt/sophos-av/bin/savlog --category=update -100

Looking at the other log I see that savd is being restarted very frequently, so this may be related to your issues.

In SAV: UpdatePeriodMinutes is relative to the start of savd.

In 9.14:

• The first update (check) happened UpdatePeriodMinutes after savd starts.
• savupdate restricts Sophos updates to no more than once per hour.

In 9.15:

• The first update (check) happens 5-10 minutes after savd starts.
• Subsequent update (checks) happen UpdatePeriodMinutes after the previous update.
• savupdate doesn't restrict Sophos updates.

This was a deliberate change to support temporary machines and new installs, which weren't getting updates quickly enough.

I suspect this might explain some of what you are seeing, since I was in the other log you gave me that savd is being restarted very frequently.

confuse ...

This problem begining after version update ( 9.14 to 9.15 in 21th the current month ).

This the fact !!!

I has solved it.

I adjusted for 60 minutes and reboot da system.

Then I aguard the Sophos update normaly including 60 minutes after.

Right after adjust for 1440 minutes ( 24h ) and now it work perfectely.

It was probably some bug

Thank you all !!!

The problem return after reboot !!!

Hello

I am not satisfied with this every hour update,  so I changed also

/opt/sophos-av/bin/savconfig query UpdatePeriodMinutes
1440

Here is how I managed

Modify the script /opt/sophos-av/engine/.sav-update.systemd.start.sh

Last line is now

exec "$SAVUPDATE" >>"$SAV_UPDATE_LOG" 2>&1 </dev/null || true

Modify the /lib/systemd/system/sav-update.service

Enable it

systemctl enable sav-update.service

That way I have only one update after boot

Hi grand toubab 

Exists some solution that I configure for not update after boot ?

Now it update every boot and respect configuration of 1440 minutes ( 24h ).

Terefore, the proccess loaded at boot for preload are afected.

Thanks very much.

savupdate will run during sav-protect start up script if:

1. On-Access is enabled
2. Talpa is an enabled on-access method
3. SAV doesn't have a Talpa Binary Pack available

savupdate will run 5-10 minutes after savd starts up, unless updating is disabled.
