Hello,
I am one of the maintainers/developers of HMDB, we recently had to limit
the number of hits per minute to HMDB as some users were sending huge
numbers of requests for an extended period of time which was affecting
performance of the site. Any hits that exceed the rate limit will get 503
errors. I have recently received a complaint from a user of your MzMine
software that the software is throwing an error due to a 503 error being
returned by HMDB implying it is exceeding the access limit.
I would like to modify the limit to enable your software to keep working,
but need some information from your team to enable me to do so. At what
rate does MzMine grab pages from HMDB? Also how many do you grab at a time?
An easy solution would be for me to increase the allowed burst size or
allowed rate to a high enough number to allow the MzMine software to
continue to function properly.
Kind regards,
Mike
PS here is the message from the user:
I am currently using mzMine, and searching for metabolite identification
> using the HMDB. During its search, the following message appears:
> 'Could not connect to HMDB: java.io.IOException:
> Server returned HTTP response code: 503 for URL
> http://www.hmdb.ca/metabolites/HMDB11601(null:-1)'
Is there anything that I could do to rectify this problem and return all
> metabolite possibilities?
