[Solved] Incerasing server load - Too many "send_file_updates" processes

Seafile Server

Hello,

I am running Seafile Pro 7.1.7 under Debian Buster (10.8).
This morning the server went down under a very important charge (42 according to top…).
Seahub and Seafile were not responding, so we decided to restart everything.
Later on this afternoon the problem occured again.
We have a very important CPU load with many pyhton processes ran by seafile user.
If we look at the different processes here is what we have :

   580 ?        Ssl    0:00 /usr/bin/python3 /usr/share/unattended-upgrades/unattended-upgrade-shutdown --wait-for-signal

  4251 ?        S      0:00 /bin/sh -c "/usr/bin/python3" "/seafile/seafile-pro-server-7.1.7/seahub/manage.py" "send_file_updates"
  4252 ?        R      6:35 /usr/bin/python3 /seafile/seafile-pro-server-7.1.7/seahub/manage.py send_file_updates

  4270 ?        R      6:03 /usr/bin/python3 /seafile/seafile-pro-server-7.1.7/seahub/manage.py send_file_updates

The last two lines keep repeating for a while, load the server and jamming the service.

Could anyone tell me what is going on ?

Thanks !

Hello Seafile Community,

OK we found the problem… We’ve changed the Seahub mail server configuration earlier this week and obviously it was erroneous. We switched back to the old mail configuration, restarted the services and everything went back to normal.
I hope this will help someone else :slight_smile:

Well… the problem has finally not been solved… The server load started to rise again this morning.
I sent a shared linked successfully, so the the SMTP parameters are not wrong…

Hello,
We flushed the UserActivity table within the seahub-db database and it solved the problem.
At least, for now :slight_smile:

Hello RomainC

Is this Problem still solved on your side?

Hello @phroton,

Yes :slight_smile:
We had a problem during a Seafile Server upgrade and this table hadn’t been upgraded properly.
It worked for some time and the problem began later… So we suspected many other things, but flushing the table allowed it to work normally again.

I hope this will help you.
