we see frequent errors with mdm server on talend studio -6.3.1
while we are making connection to any of the mdm server on Talend , we are receiving timeout error
while making test connection we see unable to connect server please check your connection settings, when looking in to the log of the same server we see as below :
INFO [SharedFileLocker] Database /var/opt/TalendMDMServer631/data/activemq-data/localhost/kahadb/lock is locked... waiting 10 seconds for the
database to be unlocked. Reason: java.io.FileNotFoundException: /var/opt/TalendMDMServer631/data/activemq-data/localhost/kahadb/lock (Permission denied)
As temporary fix we are removing lock folder from var/opt/TalendMDMServer631/data/activemq-data/localhost/kahadb/and restarting the tomcat , it help us to fix the issue at that moment but we cannot find any perminant fix can any one help us on this ..
FYI - MDM server is up and running
Https URL is working fine and able to login
Tomact process is running - while we experienced issue
Only we observed Http connection is getting lose.
I have discussed with our developer, and was told that this issue might be caused by the third component ActiveMQ and it occurs randomly, we can't reproduce it on our side. If you always have this error or you have a fixed steps to reproduce it, please report a jira issue on our bugtracker, it will helps us to investigate it.
