CONFIG_LOG_STRDUP_BUF_COUNT

Number of buffers in the pool used by log_strdup()

Type: int

Help

Number of calls to log_strdup() which can be pending before flushed
to output. If "<log_strdup alloc failed>" message is seen in the log
output, it means this value is too small and should be increased.
Each entry takes CONFIG_LOG_STRDUP_MAX_STRING bytes of memory plus
some additional fixed overhead.

Direct dependencies

LOG_MODE_DEFERRED && !LOG_MINIMAL && !LOG_FRONTEND && !LOG_MINIMAL && LOG

(Includes any dependencies from ifs and menus.)

Defaults

• 8 if BT

• 4
