huge amount of +~JF****.tmp files in /var/cache/tomcat7/temp
<p>In my tomcat temp folder, I have 2.5Gb of <code>+~JF****.tmp</code> files, the file sizes are either ~750K or ~23M</p>

<pre><code>$ pwd
/var/cache/tomcat7/temp
$ ls -lt
-rw------- 1 tomcat tomcat 23278008 06:47  5 Th08 +~JF2247741302721424357.tmp
-rw------- 1 tomcat tomcat   773236 06:47  5 Th08 +~JF2626850872018060030.tmp
-rw------- 1 tomcat tomcat   750984 06:47  5 Th08 +~JF6955350201064404318.tmp

</code></pre>

<p>I did you searching for this problem but all I found is about Jasper Report font problem which doesn't make sense to me, my project is not using Jasper.</p>

<p>do you have any idea why?</p>

<p>thanks</p>
