We are running a .Net website based on SDL Tridion 2013. We are getting intermittent ClassNotFoundException from PageLink. Below is the stacktrace from the exception.

This error shows randomly once a day and then restarting IIS resolves the error. We are using the 32 bit version of Tridion runtime libraries for the presentation side. The version of Java on the presentation server is 1.7u40. Please advice.

  • Hi, Did you get any resolution for your issue, we are also facing the same issue. Nov 9 '14 at 11:44
  • @rdhaundiyal No resolution yet. Nov 10 '14 at 12:07
  • Are all messages for java.lang.ClassNotFoundException on com.tridion.linking.PageLink or do you see this come up for other classes as well? Nov 11 '14 at 2:52

Check the step no 21 on Tridion documentation which talk about disable recycling of the Application Pool, though this has not resolved our issue completely but the frequency has reduced and we are still monitoring


Please ensure that you are using correct version of xmogrt.dll file. Note: The file size of the 64 version is 1,123kb, the 32bit version is less.

  • checked the filesize of xmorgrt.dll. It is 900kb (x86 version). Sep 7 '14 at 8:43
