There is no "memory leak" per se - just the propensity to use more memory than would seem to be needed (based on index size).
Using the FixedThreadLocal along with the modified TermInfosReader (that uses it), the memory problem is resolved. If you are not seeing that, then you have some other memory leak in your application. -----Original Message----- From: Fernando Padilla [mailto:[EMAIL PROTECTED] Sent: Friday, May 12, 2006 1:35 PM To: java-dev@lucene.apache.org Subject: Re: LUCENE-436 hmm. So what you're saying is that there is a "memory leak", but very very noticeable with large RAMDirectories (like what we have)... With a 5M directories, it seems to be leaking atleast 5M per hour, depending on queries.. even on our 1500M VM they run our of memory over 24 hours. So I guess we have no choice but to use FSDirectories? The FixedThreadLocal patch doesn't seem to have helped afterall..
