Filelist webdav Fatal error: Allowed memory size of 134217728 bytes exhausted

[JVanDamme]

I’m running Kopano on a UCS server, release 4.4-4 errata617, all software updated.
kopano-webapp 3.5.14.2539+111.1 all
kopano-webapp-plugin-files 3.0.0.0+118.3 all
kopano-webapp-plugin-filesbackend-owncloud 3.0.0.0+54.3 all
kopano-webapp-plugin-filesbackend-smb 3.0.0.0+36.3 all

Trying to add a webdav share in options->files of the webapp always results in a green light and a tooltip “Account is ready to use”, the quotum info is reported correctly, but every connection is followed by a “Http 500 Internal server error”.

Verifying /var/log/apache2/error.log one can see that

• kopano doesn’t use memcached (why?) and
• the script to list all files exhausts the memory limit set in php.ini and throws the 500 error.
  (error.log heavely edited)…

Adding a smb share functions correctly.

Can anyone please give me a hint to solve this problem?
Thx.

Hi @JVanDamme,

a pre-final version of the files plugin was accidentally uploaded with the last WebApp update, meanwhile a new WebApp app version has been released with the correct files plugin (and instructions in the readme how to downgrade). Can you “update” to this version and try again?

Some more details in https://forum.kopano.io/topic/3212/files-plugin-causes-problems/13

@fbartels
I downgraded as you advised to
kopano-webapp-plugin-files 2.1.5.305+101.2
kopano-webapp-plugin-filesbackend-owncloud/onbekend 2.1.0.87+42.5
kopano-webapp-plugin-filesbackend-smb 2.1.0.50+31.5
and now at first glance everything is working as it should.

Thx!!
