 I am using regex match to validate some values but after 20.1 upgrade system is very slow &amp;amp; appian support team is saying it is due to regexmatch. 
 Can regexmatch go to long running process or infinite loop( no loop has been use to in regex</description><dc:language>en-US</dc:language><generator>Telligent Community 12</generator><item><title>RE: Regex Issue</title><link>https://community.appian.com/thread/84260?ContentTypeID=1</link><pubDate>Tue, 03 Aug 2021 06:57:00 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:bdc1bbe5-ff8c-4300-ab57-f9a86e0c44b3</guid><dc:creator>yogeshc0001</dc:creator><description>&lt;p&gt;Hi Abhay,&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;We are also facing similar issue. Did you find any root cause for this issue ?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Thanks,&lt;/p&gt;

&lt;p&gt;I&amp;#39;m not saying regex is bad; but it simply may be overworked because it&amp;#39;s being overutilized.&amp;nbsp; Try limiting it to those use cases Appian CAN&amp;#39;T support without regex.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Regex Issue</title><link>https://community.appian.com/thread/81469?ContentTypeID=1</link><pubDate>Sun, 09 May 2021 11:24:45 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:550f3891-c7c6-4589-a092-5e3678e56b46</guid><dc:creator>Abhay Giri</dc:creator><description>&lt;p&gt;Execution time and other seems fine to me, i checked but i am not able to get how regex can be hit thousand time automatically.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Regex Issue</title><link>https://community.appian.com/thread/81468?ContentTypeID=1</link><pubDate>Sun, 09 May 2021 11:19:32 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:7cb23577-4b18-4e2b-a1e0-edcc6833900c</guid><dc:creator>Stefan Helzle</dc:creator><description>&lt;p&gt;OK, we need more details to be able to help.

&lt;p&gt;Check&amp;nbsp;admin console / monitoring / rule performance for rules using regex and check execution times&lt;/p&gt;
&lt;p&gt;Try to isolate the issue&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Regex Issue</title><link>https://community.appian.com/thread/81467?ContentTypeID=1</link><pubDate>Sun, 09 May 2021 11:15:34 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:32bb26d9-471f-45b9-9a55-ae7c0c33a27d</guid><dc:creator>Abhay Giri</dc:creator><description>&lt;p&gt;Support team only told us about the regex.
