http://koha.1045719.n5.nabble.com/file/n3339398/z395_error.png Hello everbody, I would like to ask for your help for my problem about KOHA used in my library. For your information, my koha version is 2.29 and running on linux OS n mysql. Lately, I face problem with z.39.5 searching. I got error like picture above when I try to search for record for example in z3950.loc.gov, in log it say premature end of script. After searching for possible factors, it show that it should be port to the servers has been blocked. so, I forward this case to my network administrator and he open all port, then it is ok. But a few days after, the problem coming back, but this time not a few port that error to connect, but this time all of it..But this error is not consistently happen mean sometime the function is ok..Usually this problem happen at morning and after a few hours, the function is ok. sometime there is no error for a day and sometime the error come for the whole day. Again, I forward this probrem to my NA, but this time he say all port has been allowed and nothing wrong with network configuration. And he suggest that the problem is coming from KOHA script that maybe doing telnet to the z39.5 servers too frequently that caused KOHA IP address was blocked for a while, he also stated that the traffic from KOHA server is too high reaching 12 TB eventhough there is not so many staff use it. It is right about it? I would like to ask for your opinion and help about this problem. Thank you for your attention.. I really hope that I can fine the exact factor of this error. -- View this message in context: http://koha.1045719.n5.nabble.com/Z39-5-error-tp3339398p3339398.html Sent from the Koha - Discuss mailing list archive at Nabble.com.
