Hi all,
I have a Java webapp using a mysql database. It all used to run well, but I
now frequently get the following error:
2005-09-15 11:33:32,115 [Thread-23] ERROR rotation -
com.mysql.jdbc.CommunicationsException: Communications link failure due to
underlying exception:
** BEGIN NESTED EXCEPTION **
java.io.EOFException
STACKTRACE:
java.io.EOFException
at com.mysql.jdbc.MysqlIO.readFully(MysqlIO.java:1842)

at com.mysql.jdbc.Connection.execSQL(Connection.java:2297)
at com.mysql.jdbc.Statement.executeQuery(Statement.java:1183)
I cannot really say when this started, but I did not get the impression that I
changed anything in my software. It also seems that this is not restricted to
certain queries, but is accidental. My configuration is Suse Linux 9.1,
MySQL-Max-4.1.5-0 (the binary rpm from mysql.com),
mysql-connector-java-3.1.7, Java 1.4.2. I did not find anything about how to
resolve this and also not a real explanation what the error means.
Any ideas?
Thanks,
Stefan
