INFO [webscripts.connector.RemoteClient] [http-8080-2] Error status 408 Read timed out

[nenad982]

Hi all,

I am experiencing the following problem. I had been created script that will be wrapper script for Share site creation/update. It was required because Alfresco is just used as repository to other front-end application and I used

org.apache.commons.httpclient.HttpClient‍

and called alfresco's scripts that will do the work. So I can create a site in one call or update site in separate call. But I have one corner case when I am creating site with MODERATED visibility so in that situation because of permissions on site's document library I have first to create site with PUBLIC visibility and after that to update it to MODERATED (just after few lines of code). So I am creating record in db (creating Share site using Java API) and after few lines of code I am trying to update record (site) and change visibility from PUBLIC to MODERATED and I received:

But after this error site has been updated as I expected and (visibility is MODERATED). So on UI I don't see any problems just in log file. Also what I noticed when I just create a site with PUBLIC visibility for example (without updating it after few code lines) everything is ok. And if I update a site afterwords to change visibility to MODERATED everything works as expected without errors in log. For updating site I am always using the same code snippet (when I am updating site after few lines of code after creation or when I update site as separate call).

I investigated this issue and I tried to change following options in MySQL db: innodb_locks_unsafe_for_binlog = 1 and innodb_lock_wait_timeout = 500 but nothing helped.

Do you have some suggestion?

Thanks…

The exception you have mentioned is read time out.
When your calling application is making a webscript call to alfresco it must have had timed out for that instance and hence given you the exception. Possibilities could be alfresco was momentarily not responding to the request for sometime and hence from your calling application it timed out.

Hi romschn,

thanks for your answer. I also concluded that from the exception but I don't know why this happening. It seams that problem is in HttpClient. Do you maybe know why this is happening EACH time?

Thanks…

Hi Ramesh,

In Alfresco suddenly we getting error

[webscripts.connector.RemoteClient] [http-bio-8081-exec-14] Error status 408 Read timed out
java.net.SocketTimeoutException: Read timed out

This happening during document processing in alfresco

Does that mean that each time you are trying to create a MODERATE site, you are every time getting the mentioned exception? If that is the case then could you please share the code snippet of how you are trying to create a site and then setting up its visibility to MODERATE. This will help to look further into it and will help to find out what is causing the issue.
