<p class="MsoNormal"><span lang="EN-GB">At Finnish Heritage Agency we have had occasionally some problems with our Oskari application’s performance. At the server, that can be seen as bigger CPU load than normally. Top processes command gives a list like that:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB">So it looks like there is a java process by jetty which takes more of cpu than there is available. When this process starts, the application is unable to work properly.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">My question is, has anyone else ever encountered similar situation? Or has any idea whether this kind of java-process is normal with Oskari? Or, what that process might do when it is taking so much processor power?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I know that this is difficult to answer, but I’m just hoping that someone has had the same situation somewhere and could maybe give some good tips to solve this annoying problem…
