Hi all,
I've seen a few other people asking about this around the internet (eg.
http://www.mail-archive.com/google-appengine@googlegroups.com/msg34608.html,
http://markmail.org/message/o35btiibcsqurenv) but it appears that no one has
got to the bottom of it yet.
I need to use the bulkloader to load a largish file (14.4Mb), the
configuration works ok as sometimes I will be able to load the file
successfully, but more often that not I get the UnknownJavaServerError shown
in the log file below... which really doesn't tell me anything. I've tried
reducing and increasing the batch size (set to 100 in log below), but that
doesn't seem to have any impact.
Could anyone please explain the inconsistent behaviour, and suggest a
solution?
Many thanks,
Mark
