Dear all, We have a really annoying problem with one of our Libraries: we can't access it anymore. We think the problem might be that the library contains too many folders/files (the error message is pasted at the end of the mail). Is there any limit for library content ? Note that we can still browse smaller libraries, so I though that we should simply split the library into smaller ones but since we can t even browse it...Any suggestions how to approach this problem? We are running a galaxy instance used by different research groups and our current setup is the following: - we have one Library per research group - we create a folder per project, under the relevant library, and add all files in these folders. Note that we add symbolic links to the real file locations (this way the large fastq files remain on owners file servers) - the files are transferred automatically to Galaxy using custom code that makes use of the galaxy API. And of course, this automated transfer now crashes as our custom code tries to read library content thru API call (to ask the user in which folder the new files should be added) PS: browsing libraries in general is really slow and gives users a bad 'user experience' (not mentioning all the extra clicks they issue because they think Galaxy did not get the request...), I am not sure why this action is that slow ( browsing small size library is also slow). I think I saw emails about this issue but I am not sure what the status is? Is there anything we could do in the code to speed this up? I am not sure this problem is related to the current post , so sorry for mixing things up. Thanks for your help! Cheers Sajoscha === error on galaxy page (nothing in the galaxy log file)
