<p>Bei einer Migration von mailcow auf ein anderes System (meistens mit einer anderen CPU) kann es unter umständen passieren, dass Rspamd meldet er könne einige (evtl. alle) <code>.hs</code> Dateien nicht laden, da diese für eine andere Plattform (CPU) kompiliert wurden.</p>
<p>Dies hängt mit Hyperscan<sup id="fnref:2"><a class="footnote-ref" href="#fn:2">2</a></sup> zusammen einer Intel Technik zum vorkompilieren von regex schemata, welche Rspamd einsetzt.</p>
<p>Diese Funktion bringt einen erheblichen Performance Boost mit sich und ist deswegen stark in Rspamd verankert.</p>
<p>Um diesen Fehler zu beheben müssen alle <code>.hs</code> und <code>.hsmp</code> Dateien aus dem Rspamd Verzeichnis gelöscht werden:</p>

<p>When migrating mailcow to another system (usually with a different CPU), Rspamd may report that it cannot load some (possibly all) <code>.hs</code> files because they were compiled for a different platform (CPU).</p>
<p>This is related to Hyperscan<sup id="fnref:2"><a class="footnote-ref" href="#fn:2">2</a></sup>, an Intel technique for precompiling regex schemas that Rspamd uses.</p>
<p>This feature provides a significant performance boost and is therefore heavily embedded in Rspamd.</p>
<p>To fix this bug, all <code>.hs</code> and <code>.hsmp</code> files must be deleted from the rspamd directory:</p>

<p>When migrating mailcow to another system (usually with a different CPU), Rspamd may report that it cannot load some (possibly all) <code>.hs</code> files because they were compiled for a different platform (CPU).</p>
<p>This is related to Hyperscan<sup id="fnref:2"><a class="footnote-ref" href="#fn:2">2</a></sup>, an Intel technique for precompiling regex schemas that Rspamd uses.</p>
<p>This feature provides a significant performance boost and is therefore heavily embedded in Rspamd.</p>
<p>To fix this bug, all <code>.hs</code> and <code>.hsmp</code> files must be deleted from the rspamd directory:</p>
