Thanks I'll try.

BTW I'm using v1.73 and I also see since a while a lot of errors like:

internal error: file too large:  db/kernel.return_fixes (limit 4096 bytes)

internal error: dev/src/pdsw/linux/arch/arm64/include/asm/jump_label.h:38 SQL error #2: UNIQUE constraint failed: mtag_data.tag, mtag_data.offset, mtag_data.type, mtag_data.value

internal error: dev/src/pdsw/linux/arch/arm64/include/asm/jump_label.h:38 SQL: 'insert into mtag_data values (7179031484371304448, 0, 8041, '1:      b               %l[l_yes]               \n.pushsection     __jump_table, "aw"      \n              .align          3                       \n              .long           1b - ., %l[l_yes] - .   \n              .quad           %c0 - .                 \n.popsection                              \n      ');'

Trying to revert back a few months of commits and those errors disappear.
Is it related to have stale DB ?

Thanks for you help,
Cristian
