I am running Redhat 7.3, jakarta tomcat 4.1.12 and Apache/1.3.23 with mod_jk2. I am using SSL and a JNDI datasource. On startup I get the following error in Apache "(error) [jk_logger_file.c (171)]: Can't open log file ${serverRoot}/logs/mod_jk.log" but then I don't get any other errors in either Apache or exceptions in tomcat. I'd like to solve that error but the real problem is that after a day or two of running without problems all of a sudden Apache serves up impartial pages with images displayed in odd formats, images displayed over the entire page or images that are missing or sometimes a blank page with a button image or some such. I have noted this in different browsers running on different clients. The webapp does not have any static pages so everything is a jsp and the images are all in a subdirectory, i.e. webapps/artful/Images. Problem is I can't find any clue in any of the logs. I have listed server.xml, jk2.propoerties and workers2.properties below.
