  66                               <p>Several people have been reporting odd problems with Clearcase. In investigating this I checked the server log files and found a lot of:<p>

  74 <p>Searching Rational's web I saw <a href="http://www-1.ibm.com/support/docview.wss?uid=swg21125258">lock manager problems, settings and guidelines</a> which seems to indicate that we've probably already outgrown the default parameters for the lockmgr. The article talks about monitoring the server processes for a week to determine how to best set the values for lockmgr. Unfortunately we don't have a week to wait so for the mean time I simply set the following parms on the lockmgr and restarted Clearcase on the vob sever:</p>

  80 </blockquote>
  81
  82 That should give us some breathing room. Meantime I set up a quick script to monitor the number of server processes as per the article.
