I've seen the following error crop up a couple of times when loading a specific data set in the Image Analysis view. Please note, the same data set will load without issue in the 'Browse' mode:

The data set in question is a large single well multi field data set (~ 1500 fields in this example).

The image analysis view loads information for all fields in a well which can take significant time for a dataset such as this. The fact that it isn't always reproducible is likely down to general server usage/load at the time the request is made.

I believe the timeout in question and how Columbus deals with this type of large single well data set has been improved in recent releases and is set to continue in that vein but if you do see this error as a temporary workaround you could try increasing the timeout as follows.

Locate the server.proc file in the following path:

usr/local/PerkinElmerCTG/Acapella_version/AcapellaResources/AcapellaCore/StdLib/Databundle/server.proc

(it's the same file mentioned in the on screen error)



The pertinent line which we can edit is at the top of that file and reads:

proc ServerInit(polytype xml in "Either xml structure or filename", int timeout@s=120 explicit in)

You'd just need to change the 'int timeout@s=120 explicit in' to something like 'int timeout@s=240 explicit in' i.e. 4 minutes instead of 2...

After making the change it is necessary to restart the Columbus services:

$ sudo /etc/init.d/columbus restart



check to make sure all processes are 'OK':



$ sudo /etc/init.d/columbus status



and then re-test to see if waiting that bit longer allows the data set to load.
