Apache error log output

Here are some examples of errors we often see but that are of no concern:

This is seen right after a push of new CGIs and is caused by browsers having a stale version of the CGIs/css file. A bunch of these will show up right after the push, but they should subside after several minutes as browser grab new versions.

 Cannot find correct version of file 'HGStyle.css'; this is due to an installation error, referer: http://hgw0.soe.ucsc.edu/

 File does not exist: /data/apache/htdocs/js/jquery.imgareaselect-v291.js, referer: http://genome.ucsc.edu/cgi-bin/hgTracks

We also see these often but they tend to right themselves as the load on the browser waxes and wanes.

 Too many popAbortHandlers, referer: http://genome.ucsc.edu/cgi-bin/hgTables?position=chr4:150237197-150248873&hgsid=353372405&refGene=pack&hgFind.matches=NM_023119,
