I continue to encounter problems with updating KNIME, either updating the KNIME version itself, or updating Community releases. To get the new KNIME 2.5.2 release on required me to update the modules a couple at a time, choosing them all always results in an error. Same applies for community releases, they have to be done a couple at a time too.
Both myself and my colleagues encounter the same problem, and it occurs on my home PC too. Additionally, a number of participants at the KNIME UGM reported having similar issues in getting updates to go on.
I dont believe its an internet related issue. I have been watching the update process and notice that it always completes the downloads as it shows the total x Mb of x Mb has been downloaded. As soon as the internet download is complete, KNIME appears to do nothing for about 5 minutes and then reports the error. If KNIME gets as far as mentioning its committing the provision, then it will always work. Consequently the issue seems to arise somewhere between the download being complete and committing the provision.
I have played around with the xmx in the ini file from 512 to 1024 to 1536 without any improvement.
My PC is Windows Vista 32bit 3Gb RAM, and Office PC is Windows XP 32Bit 4Gb RAM.
I hope this can be rectified as it is very time consuming getting the updates to apply.
