If it was load-related, it may mean that some Apache settings need to be adjusted – in that case, it wouldn’t be a VuFind-specific problem.

Subject: Re: Site crashed
The reporter said they have over 50 user using it in the same time, the crash happened, she has asked some of students close the site then the site came back. it is terrible if this the reason. I really don't think so.

So this problem started apparently by itself and also went away apparently by itself?
The first error, regarding RowGateway, seems to indicate some kind of database problem, but without
a fuller backtrace, it’s hard to guess exactly what the cause was.
The second error, involving Composer, is even stranger – not sure why VuFind would suddenly have
trouble loading vendor files, unless somebody tried to run a Composer update unexpectedly.
Is there any possibility work was occurring on the server at the time of the error? Do you have any
other clues to share?
I got a report and said " the web site was crashed" and after a while it come back. I checked log file and found the error messages as following (two kind errors). Anyone know
what it means ?
