Problems with solr when migratin from Alfresco 5.2 to 6.2

[iohann95]

I'm having serious troubles trying to migrate my data from alfresco 5.2 to 6.2.

Everything works but when the reindex is happening, all sort of errors happen, the one that are blocking me this time is:

After that error the reindex seems to stop.

Thats a strange error to happen since I didn't brought the index from the old version since it's not compatible.

I'm using the alfresco community docker installer:

Hi Johann,

We are having the same problems, so I read you post. But I cannot figure out what exactly you did to solve your problems.

Can you explain??

Best regards,

Wybrand.

Hi Wybrand,

Basically I allocated a bunch of ram to Solr service, if I recall I put 6144mb on mem_limit. I also changed Xmx and Xms to 4608mb. I intentionally left some wiggle room because otherwise the docker container kept crashing with error 137.

tlog when not comitted seems to also eat alot of HDD, so mind that also.

After reinxed completed I changed back the configurations. I'm no expert, but that's what worked for me.

Hello,

I encountered this issue. Where did adjust the solr memory it is in sorl GUI? 

Thank you.
