I am new to Koha. I am exploring Koha for possible use on future projects. I have Koha running with 52,000+ bib records loaded. No item or patron records. I exported some records and made some edits on them. Now I am trying to reload them and overlay the existing record. The reload gets stuck and eventually times out. I split up the load and have loaded several records but it gets stuck at a certain point. I have narrowed it down to a single record. (But there may be others.) On the stage MARC for import I upload the file with a single record. Enter a comment: blah blah Record type: bibliographic Character encoding: MARC 8 Modify record using template: Do not use Record matching rule: Recnum [the contents of tag 999c] Action if match: Replace existing record with incoming Action if no match: Ignore incoming record Check for embedded item record data: No How to process items: Ignore items I am using Koha version: 3.14.04.000 It loads other records, but on this one (and possibly others) is stops. It will eventually time out. The record that does not load is: =LDR 00702nam a2200241Ii 4500 =001 2828430 =008 770323s1934\\\\lv\a\\\\\\\\\\000\0\lav\d =035 \\$a.b10127641$bcar $c- =040 \\$aEXN$cEXN =041 1\$alaveng =049 \\$aEXNh [326608]$c1 [326608] =090 \\$aBV3640$b.W375 =100 1\$aWatson, Charles Henry,$d1877-1962. =245 10$aPee zilwekehdejeem /$cK.

BTW: It has reloaded on control number before but 40% of my records do not have a control number. It has also reloaded on marc tag 035 but I haven't been able to do that for the past week. Please point me in the right direction. Thanks Steve Sowder Systems Librarian sowder@andrews.edu Andrews University
