We frequently experience high load on the SNPsnap web-server. Although we are happy about the demand and use of SNPsnap, it unfortunately means that the server crashes from time to time.
When the SNPsnap server has crashed, it returns the page '
Internal server error (code 500)
' after you've submitted your job.
If you get this error message, you will usually have to wait one or two hours (but sometimes up to 24 hours) before the server has rebooted and is online again.
If the server crashes all running jobs are lost (and you will not receive an email notifying you about the job completion).
You should only contact us
if the problem persists for more than two days.
We are currently looking into solving this problem by 1) emailing users if their jobs failed because of server overload; and 2) upgrading the SNPsnap server to better support the usage load.
We are sorry about the inconvenience that this downtime may cause our users.
To help minimize the downtime, we ask our users to be mindful about the number of jobs they submit simultaneously. Do not submit multiple jobs containing tens of thousands input SNPs as this is likely to crash the server.
