MEM-FLUSHBLOCKS

Syntax
MEM-FLUSHBLOCKS <number of blocks>
Variable
VT_MEM_FLUSHBLOCKS
Default
1024
Description
This option controls when a background thread flushes trace data into the flush file without blocking the application. It has no effect if
AUTOFLUSH
is disabled. Setting this option to a negative value also disables the background flushing.
Flushing is started whenever the number of blocks in memory exceeds this threshold or when a thread needs a new block, but cannot get it without flushing.
If the number of blocks also exceeds
MEM-MAXBLOCKS
, then the application is stopped until the background thread has flushed enough data.
