&lt;ul&gt;
	&lt;li&gt;B: inserts stall coinciding with bump in &quot;log files used&quot; and &quot;log files prepared&quot;&lt;/li&gt;
	&lt;li&gt;D: inserts resume on next checkpoint&lt;/li&gt;
	&lt;li&gt;during stall &quot;log force write operations&quot; and &quot;log force write operations skipped&quot; are very high (8 M/s)&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Following stack, captured at C above, seems to be typical of stalled operations:&lt;/p&gt;

&lt;p&gt;Attaching diagnostic.data and stack traces (with timestamps) captured every 5 seconds during run.&lt;/p&gt;

&lt;p&gt;Note: above repro was with the journal on SSD, so it reached the point where the &quot;log files used&quot; and &quot;log files prepared&quot; counters were bumped fairly quickly, before the next checkpoint. With journal on HDD, the problem still reproduces, but more the operation rate is much slower, so it takes much longer (several checkpoints) to reach the point where &quot;log files used&quot; and &quot;log files prepared&quot; bump, at which point operations stall until the next checkpoint.&lt;/p&gt;</description>

previous versions already as a backport to the v3.2 branch. For example,&lt;br/&gt;

this commit replaces that change with 1f4aaa44 itself.&lt;/p&gt;

This should be fixed by the latest drops into master and v3.2 (for 3.2.7).&lt;/p&gt;

&lt;p&gt;Note that this pause would only happen in single-threaded workloads: when there was a log file switch, &lt;tt&gt;log_flush&lt;/tt&gt; was waiting at the beginning of the new log file for the write point to advance, but it wasn&apos;t moving into the new log file until something was written to it.  With multiple threads writing, something would be written quickly and the stall wouldn&apos;t happen.&lt;/p&gt;</comment>
