SQL fout met image import

Hallo,

Ik heb op mijn site een upgrade uitgevoerd van Drupal versie 5 naar versie 6.
Alles werkt behalve de image import module.

Als ik foto's wil importeren krijg ik de volgende foutmelding:

Warning: Got a packet bigger than 'max_allowed_packet' bytes query: INSERT INTO watchdog (uid, type, message, variables, severity, link, location, referer, hostname, timestamp) VALUES (2, 'php', '%message in %file on line %line.', 'a:4:{s:6:\"%error\";s:12:\"user warning\";s:8:\"%message\";s:1535654:\"Got a packet bigger than 'max_allowed_packet' bytes\nquery: UPDATE batch SET token = '6a793cafe3298c1f4552a6a72de09001', batch = 'a:10:{s:4:\\"sets\\";a:1:{i:0;a:11:{s:7:\\"sandbox\\";a:0:{}s:7:\\"results\\";a:0:{}s:7:\\"success\\";b:0;s:5:\\"title\\";s:29:\\"Afbeelding aan het importeren\\";s:16:\\"progress_message\\";s:29:\\"Importing @current of @total.\\";s:10:\\"operations\\";a:1:{i:0;a:2:{i:0;s:22:\\"_image_import_batch_op in /home/site/domains/site.nl/public_html/includes/database.mysqli.inc on line 128

Ik heb op de database al een repair gedaan.

Weet iemand een oplossing van dit probleem?
