HI  All 

I am a newcomer in the alfresco, this system in the use of a week or so, via the web login will be caton, unable to use, after restart the system to normal, the attachment is the log

It seems alfresco cann't get db connection from connection pool,most likely that new connections from postgresql are not possible.
You an try to increase max connection and share_buffer of postgresql by modifying following parameter in postgresql.conf
max_connections=1024
share_buffer=**

Hi There,

I have reviewed your log file. Your database connection has reached to limit and alfresco is not able to open further connections due to lack of buffer space (I assume you are having enough disc space and memory).

You should be editing <<ALFRESCO_HOME>>\tomcat\shared\classes\alfresco-global.properties file and increasing value of db.pool.max (open connection). This is a temporary solution to your problem. There could be two root cause of your problem.

1. You have not sized Alfresco properly. [You can refer to this link to know more about it : Luis Cabaceira on Alfresco  ]

2 . Connection leakage in your customization. If you have done any customization, check whether the resources are closed appropriately and you have followed best practices for customization.

Certainly, there might be more reasons to your problems as well and it depends on which alfresco version you are using.

If you face issues after following the above steps, please share more information.

Thanks,

Kalpesh
