Hi,
we have a Problem with Tomcat/MySQL which causes our webapplication to stop
working.
After a restart of Tomcat and MySQL it works again. But we have to do this a
few times a day.
First some Info about the Server and versions:
- SUSE LINUX Enterprise Server 9 (i586) Patchlevel 4
- jakarta-tomcat-5.0.19-29.18
- mysql-shared-4.0.18-32.37
- java2-jre-1.4.2-129.48
- java2-1.4.2-129.48
Often the follow error occurs the application is blocked:
Mar 12, 2009 9:25:19 AM org.apache.ojb.broker.util.logging.CommonsLoggerImpl
error
SEVERE: Can't lookup new HighLowSequence for field id using sequence name
SEQ_t_xx_xxx
org.apache.ojb.broker.TransactionInProgressException: Connection is already
in transaction
at
org.apache.ojb.broker.accesslayer.ConnectionManagerImpl.localBegin(Unknown
Source)
at
org.apache.ojb.broker.core.PersistenceBrokerImpl.beginTransaction(Unknown
Source)
…
This error is always in relation with the following warnings:
12 Mar 09:20:31 22794068 [http8080-Processor16] WARN
ch.XXX.XXX.dh.PersistenceSession -
org.apache.ojb.broker.PersistenceBrokerException:

12 Mar 09:25:19 23081606 [http8080-Processor16] WARN

Does anybody have a hint?
Thank you
