OpenBSC relating IMSI/IMEI

Hi, I’m currently facing a strange issue where the number of entries in the subscriber table is different from the number of entries in the equipment table, therefore I cannot consistently relate each IMSI to its correct IMEI. I also had another issue where I have the same number of entries but the ID’s of the rows are different as shown below: Subscriber table Equipment table ID IMSI ID IMEI 1 XXXX 1 XXXX 2 XXXX 2 XXXX 4 XXXX 14 XXXX Does anyone know why this is happening, and how can I correctly relate each IMSI to its corresponding IMEI ? Best regards, Robert,
